Abstract: An optical pulse pattern generator can generate optical pulse signals with various periods and patterns. It supplies an optical pulse from an optical pulse source to a variable optical delay line circuit including cascade-connected characteristic-variable asymmetrical Mach-Zehnder interferometers via an optical combiner and splitter. The optical pulse is fed back to the optical combiner and sputter from the final stages of the cascade-connected characteristic-variable a symmetrical Mach-Zehnder interferometers via an optical exclusive OR circuit and optical amplifier. Making directional couplers with variable coupling ratio, and directional couplers with variable coupling ratio in operation can cause the final stage of the cascade-connected characteristic-variable asymmetrical Mach-Zehnder interferometer to produce a random pulse train.

Abstract: The present invention relates to an NH3 injection rate control technique for suppressing an NO X concentration to below a desired NO X concentration through the use of an NH3 injection rate reaching a minimum. In the NH3 injection rate control method for an NO X removal apparatus according to the invention, an operating area of the NO X removal apparatus is divided into a first area in which a molar ratio of an NH3 injection rate with respect tc an NO X flow rate at an inlet of the NO X removal apparatus is smaller than a molar ratio at a minimum point where an NO x concentration assumes a minimum value and a second area in which the molar ratio vs equal to or larger than the minimum point molar ratio, and a virtual NO X concentration with respect to the molar ratio is set according to a virtual characteristic line which varies monotonicallv to stride across a desired operating point without rising with an increase of the molar ratio from the first area to the second area. Moreover, feedback control is implemented for adjusting the NH3 injection rate with respect to the NO X flow hate on the basis of a deviation between a desired NO X concentration and the virtual NO X concentration in a direction that the virtual NO X concentration is brought close to the desired NO X concentration.

Title: Gas burner
Inventor: O'DONNELL MICHEAL J
IPC: F23D14/02
Filed: 2003-03-05
Granted: 2010-12-21
Abstract: A burner having an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element. The inlet end is further formed to define at least one primary air opening arranged to admit primary air from a source of primary air. A bluff body is located downstream from the gas orifice element and is positioned such that gas emitted by the orifice impinges on the bluff body. Rows of flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern. When used as a fireplace burner the flame ports maybe slot-like in construction and include tabs which determine the effective size of the ports. In a fireplace application, flame ports located below a crossover log, are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating looting. In alternate embodiments, the bluff body is formed by a pair of confronting depressions formed in the inlet end of the burner body. The depressions form a'pair of venturi channels which define the mixing chamber. In a third alternate embodiment, the confronting depressions are spaced apart and mount a cylindrical bluff element therebetween. The use of venturi channels eliminates or substantially reduces the incidence of light back. When used as a premix-type burner, a source of primary air under pressure is delivered to the inlet end of the burner and compensates for the restriction posed by the bluff structure, resulting in a blue flame.

Granted: 2012-02-07
Abstract: L'invention concerne des procédés permettant d'améliorer les estimations de position pour un dispositif donné, en cas de détérioration marquée de la précision. Selon une variante, on reçoit initialement des estimations de position pour un certain nombre d'émetteurs (par exemple, satellites et/ou stations de base GPS) et une série de mesures initiales (par exemple, pseudo-distances). On calcule un vecteur de mise à jour pour une estimation de position de dispositif courante. Après la détection d'une non-convergence de cette estimation vers une estimation de position cible, et confirmation, le vecteur de mise à jour est ajusté (par exemple, réduction de valeur numérique selon un facteur d'échelle), ce qui permet d'augmenter la probabilité de convergence vers l'estimation de position cible. Ensuite, l'estimation est mise à jour sur la base du vecteur de mise à jour (éventuellement ajusté). On peut déceler la non-convergence en fonction du nombre d'itérations accomplies sans parvenir à l'estimation cible, et/ou de l'inversion de phase sur deux vecteurs de mise à jour consécutifs. Il est possible d'augmenter le facteur d'échelle à chaque détection d'événement indicateur de non-convergence.

Abstract: The invention concerns inertial navigation units for aircraft. In order to improve altitude measurement accuracy, it consists in associating with the inertial unit (C_INERT) a radio sonde supplying the aircraft altitude (HAUT_ALT) relative to the ground and a terrain database (DTED) supplying a ground altitude (ALT_GND) at the aircraft horizontal position delivered by the inertial unit. The inertial unit supplies an altitude (ALT_HYB) which is corrected on the basis of values supplied by the radio sonde and the terrain database. A protecting radius (RPalt_hyb_cor) of the thus corrected altitude is calculated. For said calculation of the protection radius, it consists in calculating in particular the dispersion of the terrain altitude around the aircraft horizontal position, in a circle delimited from the protection radius of the horizontal position (RPpos_hor_hyb), supplied by the inertial unit simultaneously with the horizontal position.

Title: Discharge lamp with phosphor
Inventor: HUBER GUENTER
IPC: C09K11/80
Filed: 2004-05-31
Granted: 2013-04-02
Abstract: A discharge lamp (1) having a discharge vessel (2) which surrounds a discharge medium which emits electromagnetic radiation in the VUV region when the lamp is operating has, on the inner side of the discharge vessel wall, a first phosphor layer, which faces the discharge medium and comprises a UVA component which can be excited by the VUV radiation and is intended to emit electromagnetic radiation in the UVA region. Moreover, the discharge lamp (1) has a second phosphor layer, which can be excited by the UVA radiation and is intended to emit electromagnetic radiation in the visible region. This second phosphor layer either lies beneath the first phosphor layer or is applied to the outer side of the discharge vessel wall. This results in a lower color locus shift compared to a conventional phosphor mixture which can be excited directly by VUV radiation. (Fig. la)
